John D. Rockefeller er stóri lærumeistarin hjá Hallsteini. Hann byrjaði sum blaðberari, Rockefeller, og hevur kveikt Hallstein í øllum hansara arbeiði á hesum sama øki. "Man verður ikki millióningar av at bera út bløð, men tað kann verða byrjanini og ein lærpeningur, seinni í lívinum", sigur Hallstein.
Við speglingum av háhúsunum uttanum, standa hesi orð Rockefellers hinumegin á steininum:
"I believe in the supreme worth of the individual and in his right to life, liberty, and the pursuit of happiness. I believe that every right implies a responsibility; every opportunity, an obligation; every possession, a duty. I believe that the law was made for man and not man for the law; that government is the servant of the people and not their master. I believe in the dignity of labor, whether with head or hand; that the world owes no man a living but that it owes every man an opportunity to make a living. I believe that thrift is essential to well ordered living and that economy is a prime requisite of a sound financial structure, whether in government, business or personal affairs. I believe that truth and justice are fundamental to an enduring social order. I believe in the sacredness of a promise, that a man's word should be as good as his bond; that character — not wealth or power or position — is of supreme worth."
